Games are programmed for this CPU: when emulating, every basic instruction a game runs needs to be translated to something a PC can execute.
Instead of an Intel or AMD x86 CPU, GameCube and Wii use an IBM PowerPC CPU.While it's true the GameCube and Wii hardware is a lot slower than what you need to emulate the console using Dolphin, the hardware found in these consoles is also very different from what you can find in a gaming PC.
